Multi-axial point absorption type wave energy generation device

Abstract

The invention discloses a multi-axial point absorption type wave energy generation device. A rack is embedded on one side of a first swing, a first shaft provided with a gear is mounted on two sides of the first swing, the rack and the gear are engaged, a float is fixedly connected at the lower end of the rack, and the first shaft is connected to a first generator through a gearbox; a second swing of a square frame sleeves outside the first swing, a second shaft is rotatably connected to one side of a second swing, a third shaft is rotatably connected to the other side of the second swing, and the second shaft is connected to a second generator through a second gearbox; a base of the square frame sleeves outside the second swing, a fourth shaft is rotatably connected to one side of the base, and a fifth shaft is rotatably connected to the other side of the base; the fourth shaft is connected to a third generator through a third gearbox. By the aid of the multi-axial point absorption type wave energy generation device, wave energy of multiple waves can be directionally captured simultaneously, once energy capture of the device is increased greatly, system converting efficiency is improved greatly, energy output of the device can be more stable, and generating quality can be improved.

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a multi-axis point absorption type wave energy generating device. Background technique [0002] At present, the point-absorption wave energy generation device has a wide range of applications in the field of wave energy utilization due to its high conversion efficiency, small size, and simple structure; however, limited by its own geometric shape, this type of point-absorption wave energy Generating devices often can only absorb wave energy in one incoming wave coordinate direction (such as heave), while wave energy in the other two directions (such as surge and sway) can only be converted into backward radiation and diffraction. , The form of the transmitted wave is consumed in vain. Taking the patent CN203251210U as an example, a floating ball type wave energy power generation device is disclosed, which has many advantages such as simplicity, high efficiency, and flexibility,...

Taking the patent CN203251210U as an example, a floating ball type wave energy power generation device is disclosed, which has many advantages such as simplicity, high efficiency, and flexibility, but it can only absorb wave energy in the heaving direction, and the wave energy in the other two directions is wasted It is a pity that the total amount of wave energy that can be captured by the system device during each incoming wave is greatly reduced in theory.
